Is ERA right for me?

If you’re undergoing IVF or frozen embryo transfer (FET), you’ll want to give yourself the best chance of success. Sometimes however, despite having good quality embryos, they don’t always lead to a successful pregnancy. When this happens, we may recommend having an ERA. It can tell us when your womb is most receptive at the molecular level and therefore what day is the best one for embryo transfer.

Who’s it for

You might want to use ERA if…

  • You’ve experienced repeated implantation failure with good quality embryos
  • You have a seemingly normal uterus
  • It’s beneficial to know your personal window for implantation
